Den optimala kombinationen av ljudabsorption och reflektion<\/h1>\n

Visst ljud m\u00e5ste reduceras eller elimineras, medan annat ljud ska styras ut mot en publik, hela v\u00e4gen till sista b\u00e4nkraden i ett auditorium.<\/p>\n

Gustafs paneler och Gustafs Rib l\u00e5ter dig kombinera absorption och reflektion, n\u00e5got som \u00e4r s\u00e4rskilt eftertraktat i auditorium, konserthallar eller liknande rum. Gustafs akustikpaneler har en relativt liten area f\u00f6r absorption som l\u00e4mnar kvar en stor andel reflekterande yta. Reflektionen hos en Gustafspanel \u00e4r v\u00e4lbalanserad icke vibrerande tack vare panelens tyngd och dess h\u00f6ga densitet, med start fr\u00e5n 15kg\/m\u00b2.<\/p>\n<\/div>\n <\/div>\n <\/div> \n <\/div>\n \n <\/div>\n <\/div>\n<\/section>\n\n\n\n

Bra ljudatmosf\u00e4r inom sjukv\u00e5rden<\/h5>\n

\u2022 S\u00f6mn \u00e4r viktigt f\u00f6r en patients \u00e5terh\u00e4mtning \u2013 rum med bra akustik och ljudabsorption kan minska antalet uppvaknanden med upp till 40%.<\/p>\n

\u2022 I rum med lite oljud och en kort efterklangstid minskar stressen och blodtrycket.<\/p>\n

\u2022 Bullerreducering p\u00e5 akutmottagningar och i operationssalar \u00f6kar noggrannheten med upp till 50%.<\/p>\n

\u2022 Unders\u00f6kningar visar p\u00e5 samband mellan l\u00e5g bullerniv\u00e5 och minskat behov av medicinering.<\/p>\n

Bra ljudatmosf\u00e4r inom utbildning och skola<\/h5>\n

Inom skola och utbildning \u00e4r det oerh\u00f6rt viktigt att h\u00e5lla nere bullerniv\u00e5n och bakgrundsljud som \u00e4r st\u00f6rande. En bra ljudniv\u00e5 \u00e4r \u00f6ver lag n\u00e5got att str\u00e4va efter. Om man kan uppn\u00e5 en bra ljudatmosf\u00e4r s\u00e5 \u00e4r det en seger f\u00f6r b\u00e5de elever och l\u00e4rare:<\/p>\n
